I played a very early version of the game (content ended at the sewers) and it feels like a solid proof-of-concept. This definitely feels like it could go to 4 or 5 stars with additional content and fine-tuning.

Right now the primary thing holding it back, the janky targeting/auto-targeting, is already being improved by the dev (while it still had its hiccups, the problems earlier commenters reported have been considerably smoothed) and my main complaints are just lack of things the dev undoubtedly already plans to do. For instance, the game's bot theming is a bit thin, with only five automation upgrades, and I found myself wishing that there was (for example) an "auto-sell trash" feature, or "auto-teleport to town when inventory full". I hope to revisit this when the dev has made more progress on the game. What's here is a great start!
